Part No.: IS200VTCCH1C
Manufacturer: General Electric
Country of Manufacture: United States(USA)
Product Type: Thermocouple Input Board
Series: Mark VI
IS200VTCCH1C is a Thermocouple Processor Board developed by GE under the Mark VI series. The thermocouple processor board VTCC accepts 24 thermocouple inputs of type E, J, K, S, or T. These inputs are connected to two terminal blocks on the TBTC terminal board. Cables with molded connectors connect the terminal board to the VME rack, which houses the VTCC thermocouple processor board. The TBTC can provide control in both simplex (TBTCH1C) and triple module redundant (TMR) modes (TBTCHIB).
Cable connections to the TBTC terminal boards are made at the lower J3 and J4 connectors on the VME rack. To secure the cables, these are latching connectors. Start the VME rack and look at the diagnostic lights on the front panel.
The TBTC's 24 thermocouple inputs can be grounded or unground. They have a maximum two-way cable resistance of 450 and can be located up to 300 m (984 ft) from the turbine control cabinet. On the terminal board, there is high-frequency noise suppression as well as two cold junction reference devices. VTCC performs software linearization for individual thermocouple types. A thermocouple that is found to be outside of the hardware limits is removed from the scanned inputs to avoid adverse effects on other input channels.
